Aspirated compressor technology explored for high-altitude engines

  • 23-Jun-2010 08:09 EDT

NASA awarded Aurora Flight Sciences a contract to incorporate aspirated compressor technology into high-altitude gas turbine engines. Aspiration is a technique to increase the performance of a turbine engine by sucking air into slots in the compressor blades. This increases the sustainable rate of pressure rise in the compressor, reducing the required number of compression stages in the engine. The technology allows for the design of lighter, more efficient engines to provide aircraft with greater range, endurance, and fuel economy. Aurora will investigate the interdependencies between aspirated flow requirements, weight reduction, and overall engine cycle efficiency as part of an optimization effort to maximize the capability of an engine for a high-altitude, long-endurance aircraft.
